According to a statement from Carnival Cruise Line, staff was notified of an alleged act of misconduct onboard the ship Tuesday evening.

"She was in the hot tub with a bunch of kids and she said the gentleman came and got in the hot tub," the mom told Action News Jax. "I honestly believe he scouted my daughter. He waited for that moment."

She said the man started a conversation with her daughter before sexually attacking her, leaving scratches and marks on her body.

Carnival said an adult male passenger was detained onboard. The FBI and United States Coast Guard are investigating.

"Why would somebody do that?" she said. "If he did it once, he's probably done it before. You know? So why, why don’t they run background checks on people?"

Action News Jax researched how many sexual assaults have been reported on Carnival and other major cruise lines in the past year.

Carnival had 35 reported sexual attacks in 2017 while Royal Caribbean had 17, and Norwegian had 15.

Carnival said it served more than 5 million passengers on 1,800 voyages of Carnival Ships in 2017.

We've requested information on number of passengers on other major cruise lines and are waiting for the numbers.

"It’s a shame that we guard her so much at home and then when they do go out to have a good time, this is what happens," the Florida mom said of the alleged attack on her daughter.

She said she can't wait to see her when the ship returns to Jacksonville Thursday morning.

"I just want her to move past this and I don't want it to jade her perspective on life," she said. "I'm just going to hug her and tell her it's OK, and that it's going to be OK and that it's not her fault."
